16v head on common block?

[iTurbo]

Are we talking about this with factory belt routing and tension, or the modified setup Jackson came up with and so many people run now? Or both?

I have only ever run stock setup.

I did have one stock TIII tensioner fail on me once when the bearings fell apart; which caused carnage and other failures, but have yet to ever lose a belt, oil pump, I-shaft/bearings etc.

The 8v and TIII dish is roughly the same shape, just different depths.

Both. TIII's don't eat timing belts, never have. Just wanted to clear that up cause it's misinformation. I-shafts are a different story and it has a cause.

Statement Based on all the miles you've driven a TIII? Like 500, 750 maybe?

Since the piston doesn't match the chamber, any change does mess with quench. Deeper = more deadspace where the piston doesn't match the chamber. Would be cool to see someone make a nice piston. I don't really feel like Dodge cared and a lot of engines out there seem to be designed without caring on 4 valve heads.

Carrol, I have a friend that can dispute the timing belt thing. His R/T went through several belts in a short period of time even using the tensioner tool, etc. We never did figure out why, but that was before there were solutions for the really high valve seat pressure, etc. I found out last night that the engine is still alive and running somewhere in the NE in a Daytona.

I agree. We do not have very good pistons at all. I had made some designs YEARS ago for the 8V engine, but I never got the chance to try it out..

There's always one lol. Btw, I run stock retainers(when it runs ). I'll probably shred a TB now.....

Man, don't say that! I don't wish that for you guys at all! The good thing about shredding or breaking a timing belt is the engine will stop running...unlike stripping the teeth on the I-shaft/oil pump. So, as long as the engine is still non-interference, throw a new belt on and keep going!

A bit late but the passenger side motor mount bracket is different, the 8 valve unit won't clear the cam gears.

Also, if the belt breaks, these aren't interference engines, with stock cams anyways,

I've broken tons of shitt but never a belt.
